From 3e7dde425dbcc7965398e92909d898c4ebc9fdb8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 22 Jan 2014 18:41:36 +0000 Subject: spi/pl022: Unprepare clocks while suspended When the driver was converted to clk_prepare() the suspend path didn't have any changes made so the clock remains prepared throughout the runtime of the driver. Unprepare it when suspended so that any savings that can be made as a result are made.
